Mabel is offered a job selling magazine subscriptions. She has the choice of two pay scales.
Pay Scale 1:
She can be paid $0.65 for each subscription she sells.
Pay Scale 2:
She can be paid $0.10 for the first subscription, with the wage going up $0.05 more for each subscription after the first. For her first sale she would make $0.10, for her second sale she would make $0.15, for her third sale she would make $0.20, and so on.
